Abstract: A battery pack whose resin mold is hard to peel off from the outer peripheral surface of its unit cell and which can be manufactured at low cost is obtained. The battery pack includes a flat prismatic box-shaped unit cell and a resin mold formed on the outer peripheral side surface of the unit cell. In order to prevent the resin mold from easily peeling off, a rough surface portion 25 is formed on the outer peripheral side surface of the unit cell 1 by forming numbers of minute dots by laser beam machining on the outer peripheral side surface put in contact with the resin mold.

Abstract: In a battery pack, a circuit board (10) has a plurality of external output terminals (3, 5) on the front, and a cover (16) has a plurality of openings (19, 20) that correspond to the external output terminals (3, 5) as through holes, respectively. A groove (29) filled with a resin mold (2) is formed at least between the adjacent openings (19, 20) in the back of the cover (16). A lead wire (13) is bent in a U-shape, and the curved portion (13a) of the lead wire (13) lies outside one end of the circuit board (10) in the lateral direction. A restraint member (31) is provided at the end (16a) of the cover (16) in the lateral direction. The restraint member extends backward from the end (16a) of the cover (16) to restrain the curved portion (13a) of the lead wire (13) from sticking out in the lateral direction.

Abstract translation: 在电池组中，电路板（10）在前面具有多个外部输出端子（3,5），盖子（16）具有与外部输出端子对应的多个开口（19,20） （3,5）分别作为通孔。 填充有树脂模具（2）的槽（29）至少在盖（16）的后部的相邻开口（19,20）之间形成。 引线（13）弯曲成U形，引线（13）的弯曲部分（13a）在横向方向上位于电路板（10）的一端的外侧。 约束构件（31）在横向方向上设置在盖（16）的端部（16a）处。 约束构件从盖16的端部（16a）向后延伸以限制引线（13）的弯曲部分（13A）沿横向方向伸出。
